Title: A store-house for vehicles and/or goods
IPC: E04H6/42
Filed: 1957-12-20
Abstract: 866,107. Mechanical garages and other storage systems. STIRLING, J. A. Dec. 15, 1958 [Dec. 20, 1957], No. 39597/57. Class 78 (4). In a multi-storey garage, cars are transported from the entrance to selected parking spaces, and vice versa, automatically. A car to be parked in a vacant parking space, indicated on a control panel in the attendant's cabin, is driven on to a trolley 10 in a hoist 9 which raises it to the appropriate floor. The trolley is then driven by an electric motor along a gallery 8 on rails 11 and stops opposite a selected parking space 7. Motor-driven rollers 12 supporting the car on the trolley then operate to move the car on to rollers 13 in the parking space, the rollers 13 being driven either by individual motors, or by the drive motor for rollers 12 through an automatic clutch. An automatic control circuit is described in detail and comprises a control panel provided with key-controlled switches and vacant parking space indicating lamps corresponding to each of the parking spaces. Rotation of the key in the switch effects parking or delivery of a car in or from the selected parking space. The circuitry is such that if, during the parking of one car, a switch is operated to initiate the delivery of a second car, the trolley is driven directly to the parking space of the second car from that of the first car without first returning to the entrance. The garage may be used as a warehouse for automatically storing containers in preselected storage compartments.

Filed: 1972-09-01
Abstract: 1406844 Jet pipes-noise suppression panels SHORT BROS & HARLAND Ltd 29 Aug 1973 [1 Sept 1972] 40719/72 Heading F1J [Also in Division F2] A sound absorbing panel, particularly suitable for use in gas turbine engines, comprises a perforate facing sheet 12 and an imperforate facing sheet 13 with a corrugated core 11 therebetween formed of inclined webs 14a, 15a connected by ridges 21. The webs 14a are unperforated and the webs 15a are perforated. Thus the imperforate walls 14a of the core 11  forms with the facing sheets 12, 13 a plurality of side-by-side resonating cavities. The perforate walls 15a form dividing members which divide each cavity into a first chamber 23 and a second chamber 24. The perforate facing sheet 12 is arranged so that sound impinges directly on its surface. The first chamber 23 acts as a resonator to absorb a first characteristic frequency and the first and second chambers 23, 24 together act as a resonator to absorb sound of a second characteristic frequency. Thus the chambers together absorb sound over a broad band of frequencies. In alternative embodiments, Figs. 2 and 3 (not shown), the core 11 is sinusoidal in cross-section or has the webs corrugated with flutes extending in a direction at right angles to the length of the ridges and terminating at each end a predetermined distance from the ridges. Any of these sound absorbing panels may be incorporated in the jet pipe 30 of a gas turbine engine 31 with the cavities extending in planes normal to the axis of the jet pipe 30 and so that the perforate facing sheet 12 presents a flowdefining surface for the exhaust gases. The noise attenuating performance of the panel may be enhanced by the addition of one or more partitions (37), Fig.5 (not shown) which extend axially along the jet pipe to divide each cavity into a number of circumferentially extending portions.

Title: High frequency tube apparatus
IPC: H01J23/027
Filed: 1958-12-19
Abstract: 1384866 Reflex klystrons VARIAN ASSOCIATES 19 Dec 1958 41184/58 Heading H1D In a reflex klystron oscillator the reflecting electrode is tilted relative to the beam axis to direct the electrons out of the beam after a small number of transits, thereby reducing distortion of the output signal. As shown, the beam from cathode 26 is passed through the cavity resonator 3 and is returned by the reflector 5. The latter is tilted by an angle # and the electrons are returned along a path inclined to the incident beam axis so that they leave the beam after a number of transits and so reduce the distortion of the output signal. The resonator grid 13 has a central opening large enough to permit the penetration of the electrostatic field of the negative reflector 5 into the cavity 3 to remove positive ions and to prevent positive ion oscillations and so also amplitude and frequency modulation. To reduce the effect of temperature induced dimension changes in the cavity 3, which would alter the resonant frequency, the high temperature tubular member 14 is formed of a low coefficient of expansion material and the end of cup member 12 tends to straighten with rise in temperature. This last effect is caused by the coefficient of thermal expansion of 12 being lower than that of the body 1. Similar thermal compensation can also be effected by cup 9 and by reversing the direction of lowering of the cups 9, 12 and of material with an expansion greater than that of body 1. Energy from 3 is transmitted through the iris 16 and the alumina ceramic window 17. A vacuum tight seal is formed by the nickel steel frame 18, surrounding 17, which is carried in plate 21 brazed to the body 1.
